In an environment with stable availability of resources, the population can still grow because there are enough resources for this population to survive. Option B.  The species' population can be expected to increase.

This question is related to growth models.

A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.

The population growth per capita rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

Carrying capacity refers to the maximum point at which the environment can support a growing population.

K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.

• If the population size, N, is inferior to K (N<K), the population can still grow.

• When N approximates to K, the population´s growth speed decreases.

• When N=K, the population reaches equilibrium,

• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.

So when the population size exceeds K, carrying capacity makes the population decrease in size.

But if there is a constant availability of resources, the population can still grow because there are enough resources for this population to survive. In this situation, N<K.

When resources are stable over a long period of time, a species' population can be expected to INCREASE. Option B.

The following correctly pairs a greenhouse gas with its main human source: Methane and agricultural practices.

Greenhouse gases trap heat in the Earth's atmosphere and contribute to global warming. Human activities are the primary sources of these gases. Methane is a potent greenhouse gas that is mainly produced by agricultural practices, such as livestock farming and rice cultivation.

Vehicular emissions are a source of other greenhouse gases, such as carbon monoxide and nitrogen oxides, but not methane. Chlorofluorocarbons (CFCs) are potent greenhouse gases, but they are not a significant source of emissions from the combustion of coal.

Nitrous oxide is mainly produced by agricultural practices, such as fertilizer use and livestock farming, and not by burning solid waste from homes. Carbon dioxide is a greenhouse gas produced by various human activities, including the burning of fossil fuels, deforestation, and cement production, but not by solid waste from homes.

Therefore, Methane is accurately linked with its primary human source of agricultural practices.

Explanation:

The process in cells represented by the diagram would be translation or protein synthesis.

The translation is a process in cell biology during which the genetic codes in messenger RNA are decoded into their respective amino acids and linked together by peptide bonds. The process usually takes place in the ribosome of eukaryotic cells.

During translation, the genetic codes on mRNA are read and the amino acid corresponding to each code is released. The small ribosomal unit first binds to the mRNA at the beginning. Thereafter, the tRNA binds to the start codon on the mRNA before the binding of the large ribosomal subunit to complete the initiation complex.

The common characteristic that binds the digestive juices in the liver and pancreas is that they both contain enzymes that aid in the digestion of fats, carbohydrates, and proteins. Specifically, both the liver and pancreas secrete enzymes that help break down and process food in the small intestine. The liver produces bile, which aids in the digestion and absorption of fats, while the pancreas secretes pancreatic enzymes, including lipase, amylase, and protease, which break down fats, carbohydrates, and proteins, respectively.

The liver and pancreas are two important organs in the digestive system that produce digestive juices to aid in the breakdown and processing of food. These digestive juices contain enzymes that help to break down the different components of food, including fats, carbohydrates, and proteins.

The liver produces bile, which is a greenish-yellow fluid that is stored in the gallbladder and released into the small intestine when food enters it. Bile contains bile salts, which aid in the digestion and absorption of fats. Bile salts break down fats into smaller droplets, making it easier for pancreatic lipase to break down the fats further. This process is important because fats are difficult to digest and absorb in their larger form.

The pancreas produces digestive juices that contain enzymes such as lipase, amylase, and protease. Lipase is an enzyme that breaks down fats into fatty acids and glycerol, which are then absorbed into the bloodstream. Amylase is an enzyme that breaks down carbohydrates into simple sugars, such as glucose, fructose, and galactose, which can be absorbed into the bloodstream. Protease is an enzyme that breaks down proteins into smaller peptides and amino acids, which can also be absorbed into the bloodstream.

The enzymes produced by the liver and pancreas work together in the small intestine to break down and process food. When food enters the small intestine, the liver releases bile, which breaks down fats into smaller droplets. The pancreas then releases its digestive juices, which contain enzymes that break down fats, carbohydrates, and proteins into their component parts. These nutrients can then be absorbed into the bloodstream and used by the body for energy or other functions.

In summary, the common characteristic that binds the digestive juice in the liver and pancreas is that they both contain enzymes that aid in the digestion of fats, carbohydrates, and proteins. This is important for the efficient processing of food in the small intestine and the absorption of nutrients into the bloodstream.

Explanation: Palatelets are an important role in the body's functionality. Palatelets are Blood-clotting cells, which, in-case of an injury with a result of bleeding, form blood clots to try and stop that bleeding. Regularly, unactivated palatelets move throughout normal blood vessels. The shape of unacivated palatelets are formed in a disc or plate-like shape. When blood vessels are disturbed and broken, these cells clump together, to simulate a blood clot.  

In prokaryotes, DNA replication requires a free 3'-OH to initiate polymerase activity is accomplished by synthesizing a temporary RNA primer removed by polymerase I (Option C).

During DNA replication, a temporary RNA primer is synthesized by an enzyme called primase. This primer provides the free 3'-OH group necessary for DNA polymerase to initiate the addition of nucleotides. Later, polymerase I removes the RNA primer and replaces it with DNA, ensuring accurate replication of the DNA strand.

Thus, DNA Polymerase I possesses a 3´→5´ exonuclease activity or "proofreading" function, which lowers the error rate during DNA replication, and also contains a 5´→3´ exonuclease activity, which enables the enzyme to replace nucleotides in the growing strand of DNA by nick translation.
